"""Are the crinkliness failures the objective emits real defects? (`homemaker-py-ssz`)

Not an A/B. This asks a correctness question the search cannot answer: of the
`crinkliness` failures the STOCK objective reports, how many are on a space
that architecturally wants daylight at all?

A `crinkliness` fail says "this leaf has too little exposed wall for its area".
For a bedroom or a living room that is a real defect. For a broom cupboard, a
WC, a plant room, an internal corridor or a covered courtyard it is not -- those
are ordinary buried architecture, and the fail is an artefact of applying one
daylight requirement to every space regardless of use (DESIGN.md §38.8).

Every fail is classified by the leaf's DECLARED `usage:` (§39.7), so nothing
here rests on how a code is spelled.
